New Revision: 276232
URL: https://svnweb.freebsd.org/changeset/base/276232

Log:
  MFC r275112:
  Make isp_find_pdb_by_*() search for targets in portdb in reverse order.
  
  Records with target_mode == 1 are allocated from the end of portdb, so it
  seems logical to start search from the end not traverse whole array.
